Rickenbacker 4004 pickup positions

i want to build a bass guitar with the rickenbacker bass scale i believe it's 33 1/2 inches and the hb1 ric boutique pickups in the 4004 positions. i believe the neck pickup is right next to the end of the fretboard (some say where the 24 th fret would be? when the say 24th fret they mean that the poles should be where the fret would be?). I have no idea where the bridge pickup should go... can anybody measure the distance between the point the nut meets the fretboard and the poles of the bridge pickup? Or explain to me how to find the position?
If anyone has a dwg file to pm me it would be great
